Micro5 RTU

The MICRO 5 RTU is one of the latest in a long line of MICRO MOD RTUs designed for remote data acquisition and control applications. It incorporates advanced hardware and software techniques so you can implement your application in minimal time. Numerous hardware and software safeguards are incorporated into the design so you can be assured that the unit will continue to operate for many years in the most demanding field environment.

All MICRO 5s are optically isolated and come standard with 256K of battery backed RAM and 512K of program flash.

Operator Interface

The built-in operator interface (optional) uses familiar prompts
and engineering units, eliminating operator guesswork and code memorization.
The 2×16 character local backlit display can scroll through
several screens of information with a single key press.
For greater ease of use, the 20 line by 40 character backlit
display can also be used with the MICRO 5, mounting up to 5
feet away.
For greater ease of use, the LCD display
can be mounted locally on the card cage or
remotely up to 5 feet away.
Front mounted LED’s present digital I/O status and operating
status
Sealed tactile keyboard enables setpoint and mode changing.

Additional Information

Base I/O

I/O is optically isolated in groups.
I/O is modular and can be supplied with any combination of digital I/O, analog I/O and
loop, or modem.
Digital I/O: Eight digital inputs counting 128 pps, pulse duration detection with 4 ms
resolution. Four 10-amp relay outputs.
Analog I/O: Four 0 – 5V or 4 – 20mA analog inputs, 12-bit resolution. One 4 – 20mA, 12-
bit resolution analog output (optional on analog board). 24V, 160mA loop supply.
Modem: One, RS232 port. 2-wire or 4-wire Radio/lease line connection OR 2-wire dialup
telco jack.
Battery charger.

Expansion

Two vacant expansion slots on the bottom of the MICRO 5 accept any MICRO 9
expansion boards.
Module design enables easy customization with choices of modem, serial ports, printer
port, dialer, loop supply, optically isolated I/O, compact flash, etc…

I/O Connections

Individual screw terminals using rising cage clamp design are capable of accepting 14 AWG
wire.
Screw terminals plug into PC board headers. MICRO 5 can be “unwired” without removing field
wires individually.
